Lactobacillus rhamnosus

This species of Lactobacillus was originally considered to be a subspecies of Lactobacillus casei; however, further genetic research determined that Lactobacillus rhamnosus was a separate species. The bacteria from this species are often found in chains, and are gram positive, anaerobic, and rod shaped.

Lactobacillus rhamnosus bacteria typically exist in the human digestive system, but this species is also considered to be particularly important for female intimate health as certain Lactobacillus rhamnosus strains are also known to colonise in the vaginal environment. Other strains from the species are found in fermented foods such as yogurt and other dairy products, especially semi-hard cheeses.

As the properties & benefits of probiotics are strain-specific, this database provides even more detailed information at the level of the strain.
